West Bengal Chief Minister Mamata Banerjee will be travelling to Rome this September to attend the canonisation ceremony of Mother Teresa where she will be declared a saint.

"I have accepted Sr Prema’s invitation to be present at the canonisation of blessed Mother Teresa in Rome on September 4," Banerjee said on Twitter.

In March, Pope Francis had announced that Teresa, who founded the Missionaries of Charity, will be elevated to sainthood after the Church recognised two miracles she was said to have carried out after her death in 1997.

The city-based Missionaries of Charity is now led by its Superior General German-born Sister Mary Prema.

Banerjee will be accompanied by Sister Prema and Archbishop D’Souza in Rome.

Teresa, who will now be a Saint of the Roman Catholic Church, was beatified by then Pope John Paul II in a fast- tracked process in 2003.

The Nobel Laureate had spent 45 years serving the poor and sick on the streets of Kolkata.
